Project complete. Once all the fire damaged plastic was removed it was a pretty easy repair.The engine came up really nice and runs spot on. A pretty low cost repair all up. Fire damaged item was a trade at no cost. Spares came off an engine with a bent crankshaft that I also picked up for free. So just some blades, fresh oil, carby diaphram and some carby cleaner was really all that was used for this project. It didnt last long before it went to a new home!

Joe you were correct the block was un-damaged. It hardly had a mark on it.

Thanks for your help, Joe, Grumpy & Mark. I have included some photos of the finished project.
